Rihanna greets guests on the plane to her first stop on the 777 tour on November 14, 2012. The singer will wrap the tour Tuesday night at Webster Hall in NYC.

In a cheeky bit of ribbing, posters were handed out Tuesday on the flight from London to New York pronouncing Rihanna as "Missing."

The wink-wink flyer includes Ri-Ri's stats, birthday and physical description, along with the message: "Rihanna was last seen November 14 on a Boeing 777 giving champagne around. She has not been seen or heard from since. She sports numerous tattoos."

The sentiments certainly weren't lost on the singer: About five minutes before touching down in New York City, the songbird held a casual press conference that touched on some of the grumblings.
